WASHINGTON (WUSA) -- On Friday, former DC city council chairman Kwame Brown pleaded guilty to a federal charge of bank fraud, reports 9News Now's Bruce Leshan. Brown was choked up after pleading guilty and apologized to his family and to the city in a statement.

Brown is free on personal recognizance and will reportedly leave town on Saturday, reports 9News Now's Bruce Johnson.

US Attorney Ron Machen said it marks another "dark day" in the city's history as "another of our elected leaders has gone astray."

Responding to suggestions that the bank fraud charges were a fallback because prosecutors failed to find anything else, Machen said, "You think the voters would have elected Mr. Brown if they had known," he had lied to secure hundreds of thousands of dollars in loans. What then would the voters have thought if investigators had left him alone with millions of dollars in city funds, Machen asked.

Brown resigned Wednesday after federal prosecutors charged him with bank fraud for lying on a mortgage application.

Brown also was charged with a misdemeanor count related to his 2008 campaign and monies that went to his brother's now-defunct business.

Brown entered guilty pleas to both charges in US District Court and DC Superior Court. He spoke in such of soft voice that even the judges at times had a hard time hearing them.

Officials from the U.S. Attorney's Office for the District of Columbia, the FBI's Washington Field Office and the IRS are expected to talk about the case to media on Friday afternoon.

Members of Kwame Brown's staff have been offered their jobs back on Thursday. They were out of work after Brown resigned. It's not clear yet how many people are taking Mary Cheh, Brown's interim replacement, up on the offer.
